Donald Trump sold his name to a perfume, Donald Trump - The Fragrance, back in 2004. It can still be found on eBay. It was sold with this aggrandising marketing puff: "Luxurious. Confident. Persuasive. The compelling new scent for men. Power attracts." Fortunately, in another case of satirical prophecy (like that Simpsons episode with Trump as president), MAD magazine had imagined a Trump fragrance way back in 1992. They called it "The Smell of The Donald" with the strapline: "Combining the sweet smell of success with the arid stench of bankruptcy" and said it was available in "casinos, condominiums, big banks and other failed institutions".
Origins of why you might eat your hat
The saying "I'll eat my hat" conjures up such a funny visual that people have continued to use this antiquated idiom every time they're confident something will not happen. But where did the saying originate? Karl Smallwood of Today I Found Out says the saying is a streamlined version of the now defunct utterance "I'll eat Old Rowley's hat", Old Rowley being a nickname used to ridicule King Charles II, who was known for wearing foppish hats.
